Abstract
L'invention concerne un ressort pneumatique à soufflet, en particulier un ressort pneumatique à soufflet à plis. Selon l'invention, des éléments coulissants annulaires, en particulier des éléments coulissants réalisés sous la forme de rondelles de glissement, sont disposés entre des parties de soufflet adjacentes les unes aux autres et/ou entre des parties de soufflet et des parties de raccordement, des parties de soufflet, plus précisément les plis ou les bourrelets, s'appuyant contre ces éléments coulissants, lorsqu'elles sont sollicitées par les ressorts pneumatiques à soufflet à plis.
